Shakespeare once wrote that the course of true love never did run smooth. When embarking on a new relationship, it's natural, if not normal, to face many impediments. Time constraints. Conflicting opinions. Idealistic expectations. Age gaps, however, are more a minor detail than an insurmountable obstacle. This seems especially true amongst celebrities, as the age difference between several illustrious couples both past and present is considerable. And a number of those who have been fortunate enough to meet the loves of their lives refused to let a generation gap stand in their way.
